SNOW-PLOW.

SPEGIFIGATIQN forming part Of Letters Patent NO. 345,618, dated July 13,1886,

Application filed December 29, 1885. Serial No. 186,984. (No model.) I

Snow-Flows for Railways; and I do hereby declare the same to bedescribed in the following specification, and represented in theaccompanying drawings, of which Figure l is a top View, Fig. 2 a sideelevation, Fig. 3 a front end View, Fig. 4 a transverse and mediansection, and Fig. 5 a longi-' tudinal and median section, of a snow-plowprovided with my invention, the nature of which is defined in the claimhereinafter presented.

In such drawings, A denotes the bottom or base of the plow, it beinginclined, as represented, and sharp at its front edge. ported onright-angled triangular side boards, B B, extending lengthwise of it atits opposite edges. At the rear part of the base A there is a deflector,O, which extends upward from the base and has curved sides a fordefleeting the snow laterally off the base while ascending it.Furthermore there extends upward from the base, at its opposite longeredges, two vertical blades or cutters, D D, each of which projects ashort distance beyond or in advance of the front or cutting end-of thebase. Each cutter D has asharp front end, which,as it rises,inclinesbackward, as represented. The two side blades, D, are joined by a seriesof cross-blades, E, going from one to the other of them at their upper"edges, the uppermost one of such bars being fastened at its middle tothe nose of the deflector. Midway between the lowermost of the said barsand the inclined baseis a blade, F,which is parallel to the base, andthere extends up from such base, across the middle of such'barF and tothe lowermost of the blades E, a cntter-bar,G. The front edges of thesaid bars E F and cutter G, I usually make sharp,

to enable them to readily enter the snow when the plow is being drivenforward against a bank of such snow. The plow thus constructed,likeother snow-plows,is to be mounted on It is supwheels to support it andto enable it to travel on the rails of a railway-track.

On the plow being .driven forward against a snow-bank on a railway-trackthe side cutters will enter the bank before it is reached by the nose ofthe base, and in so doing will operate to preserve the plow on the railsvery much better than would be the case were the side cutters not toextend forward of the said nose. Theinclined cutting edges of the sidecutters will act to keep the plow from being lifted on its firstentrance into the bank, and as the plow may be forced therein the massof snow entering it will be divided both vertically and horizontally bythe cross-blades, at the front end of the plow, and such mass in suchcondition will pass up the inclined base and in the space between theside cutters, and meeting the nose of the deflector will be separatedthereby and thrown off laterally in opposite directionsin two streams.The upright cutter G and horizontal cutter or blade F,near the nose ofthe base, by dividing the mass of snow enables it to readily separateinto four streams as it meets the nose of the deflector, and therebyrelieves the most of much resistance that would ensue to it by thedeflector were such mass in a solid or undivided state to be forcedagainst it.

I do not claim a snow-plow made as represented in either of the UnitedStates Patents Nos. 151,916, 95,449, 178,613, as in neither of such isthe snow by knives divided into four streams on entering the plow.

I claim The snow-plow substantially as described,

.consisting of the inclined base sharp at its front end,the triangularsupports of such base,

the deflector, the side blades sharp at their
